Stringed instrument nut and stringed instrument

Abstract

A stringed instrument including strings supported by bridges, which are fixed to a body, and a nut fixed to a neck. The strings are supported in a manner enabling vibration of each string. The nut includes a nut body and a fastener. The fastener is formed by pressing members and adjustment screws. The pressing members press the strings against the nut surface so that the strings are fixed to the nut surface. A projection projecting toward the strings is formed on an end portion of the nut. The strings are supported by the nut so as to contact the top surface of the projection. This enables each string to vibrate while being in constant contact with the projection and prevents each string from coming into contact with the nut or fastener. Thus, abnormal noise is not generated.

       10. The stringed instrument nut according to  claim 1 , wherein the nut body has a first end portion adjacent to the head and a second end portion located opposite to the first end portion, the projection being arranged in the second end portion. 
     
     
       11. The stringed instrument nut according to  claim 2 , wherein the support groove narrows as an inner bottom surface of the support groove becomes closer. 
     
     
       12. The stringed instrument nut according to  claim 1 , wherein the fastener includes a pressing member arranged on the nut body and a fastening member for fastening the pressing member to the nut body. 
     
     
       13. The stringed instrument nut according to  claim 12 , wherein two of the strings are pressible against the nut body by the pressing member. 
     
     
       14. In combination, the stringed instrument nut of  claim 1  and the stringed instrument for producing music comprising the head, the neck, the body and the plurality of strings. 
     
     
       15. A stringed instrument for producing music, the stringed instrument comprising:
 a body, a neck extending from the body, a head located on a distal end of the neck, and a plurality of strings, each string of the plurality of strings having a basal end fixed to the body and a distal end fixed to the head; 
 a stringed instrument nut configured to determine a point of contact between the neck and each string that extends above the neck between the body and the head, the stringed instrument nut including: 
 a nut body arranged on the neck configured to support each string;
